Last summer I made an effort to explore various watermark techniques which were doable using The GIMP. The most fascinating method I found was explained in one particular web tutorial which I am sure I bookmarked, saved to my hard drive, or both and will simply need to relocate in order to point you to it if you'd like to pursue it. The basic idea is to create and save in your ".gimp-2.x" directory a tiled pattern file (i.e. "filename.pat") which contains the text of your copyright notice and/or anything else you want your watermark to contain. I believe the text was opaque and white on a transparent background. You then load into The GIMP an image you wish to watermark. Add a transparent layer above it and "flood fill" that layer with your white watermark pattern. Then you perform a couple of funky image tricks on it before turning the opacity of the watermark layer down to almost but not quite zero. At that point it becomes virtually invisible and most people will never know it's there. Then to reveal the watermark should you ever need to prove the image is yours in a court of law or whatever... Just load into The GIMP both your unwatermarked original and the watermarked copy as two separate layers. Then change the layer mode of the upper layer to "Grain Extract" or whatever it is - I cannot right now remember. The parts which are common to both images will be opaque gray but the parts which are different (i.e. the watermark itself) will become clearly visible. This technique survives pretty much every known technique intended to defeat watermarking. I was very impressed with the idea of it.

Is vector path a gimp tool? I'll look it up. Something new to learn. Thank you! I was looking for excuses to do exercises with the GIMP, part of getting used to the new interface. Among the many improvements in 2.8, nodes and paths - in both the Lasso a.k.a. Free Select tool, and the Path drawing tool, are easier to SEE against the background of the image on canvas. Yay! The Paths Tool in the GIMP is its built in vector drawing tool. The toolbox button that turns it on looks like a pen nib. There is also a dockable dialog for managing paths, where they are handled in a way similar to Layers. This dock includes push button commands to convert selections to paths, paths to selections, and has the stroke tool for painting along paths - using the current brush, or as a line with adjustable options. Making paths in the GIMP is a portable skill: The same type of editing interface - bezier curves - is also found in full time vector editors like Inkscape, and in CAD programs. Drawing with nodes and handles has a moderate learning curve, but I think it's well worth the effort. The signature took just a few minutes to make, using the sample provided as a guide. I went looking for tutorials to point at, but came up mostly empty. Grokking The GIMP, where I learned the basics, is getting very obsolete - the Paths dock dialog and etc. have changed a lot since it was written for GIMP 1.x. With that caveat: http://gimp-savvy.com/BOOK/index.html?node36.html (See Subsection 3.1.1.4 Bezier Paths) This video provides a run through with GIMP 2.8 that should get anybody well started on their own experimentation with GIMP curves. Major clue: To adjust node handles symmetrically, hold down the shift key! Otherwise they move independently. http://jimmac.musichall.cz/demos/gimp/paths-tool2.avi Note: I don't know why this video shows the use of Transform tools on the canvas; you can't Transform vector paths in the GIMP, as far as I know.
